6f35c2d13e [directfb] Only use the pure BLIT for integer translations. 
If we have non-integer translation on a source pattern then we need to use
STRECTHBLIT (the core takes care to optimize NEAREST patterns to integer
translations so that this will only be used when interpolation is
required).

b17d0ded8c [directfb] Use the solid pattern cache.

completely bypassing the solid pattern cache.

target, with the result that the directfb rgb24 target no longer
unconditionally fails.

86356a9578 [test] Add degenerate-dash to XFAIL. 
PS (ghostscript) interprets the degenerate end-caps quite differently, and
perhaps slightly more rationally... Add this to XFAIL, until we have a
definitive specification on how we should behave.

NO_MEMORY.

610451e4a7 [directfb] Correct fixed-to-double conversion. 
The trapezoid calculations had not been updated after the 16.16->24.8
switch. Use _cairo_fixed_to_double() rather than open-coding.

8e0950ced8 [boilerplate/directfb] Gracefully handle failure to create surface. 
Simply return NULL indicating failure to create the target surface rather
than aborting the test (allowing other targets to be tested).

f2ff794426 [perf] A crude tool to visualise performance changes across a series. 
Generate a cairo-perf-diff graph for a series of commits in order to be
able to identify significant commits. Still very crude, but minimally
functional.

41c8eefc6d [output-stream] Protect against NULL write_func. 
Allow the user to specify a NULL write_func for the output stream so that
a dummy surface can be created, for example, for querying target font
options or font extents.

Currently we do not perform any sanity checks at the user entry point and
will generate a mysterious SEGV during cairo_surface_finish() - which may
not immediately be obvious that it is due to a NULL write_func.

84e4a825ff [output-stream] Accept a NULL filename 
Principally to support creating a dummy vector surface (i.e.
cairo_ps_surface_create (NULL, 1, 1)) that can be used to determine font
extents (or target font options) before opening an output file, but also
because we currently fail to do any sanity checking at the entry point.

52ea38f97b [meta] Acquire scaled_font mutex for glyph_path(). 
The caller of _cairo_scaled_font_glyph_path() is expected to be holding
the scaled_font->mutex.

299ea0580a [user-font] Review locks under error conditions. 
Simplify the error handling by only relinquishing the global
scaled_font_map mutex if we successfully insert the placeholder font. The
result is that on the error path, there are no changes to global state and
thus we can entirely skip the user-font initialisation and
re-registration.

c76a8481f3 [analysis] Check for error surfaces. 
If the target surface is an error surface, ensure that we return the
appropriate error surface. Likewise, avoid writing to error surfaces.

6b17c6da47 [type3] Acquire scaled_font mutex whilst looking up glyphs. 
When looking up the glyph in the shared scaled_font glyph cache, the
caller is required to have taken the scaled_font->mutex.

Check that the user has not passed in an inert error object before any
attempts to write to it and return the default values.

1f9f9d936b [pdf] Acquire scaled_font mutex for show_text_glyphs().

glyphs from within an smask group.

ca5f868a73 [scaled-font] Zero font extents for an error surface. 
Do not attempt to read from the error object, but just return zero
extents.

1ddf0b2a5c [surface] Reorder asserts to make no assumptions about error objects. 
If the surface is in error, then we cannot assume anything about the
validity of its contents other than the error status (and reference
count). This is for the cases were the surface is replaced by a nil
surface, and in future where the error surface may be replaced by a tiny
error object.

644e78ca4e [svg] Lock the scaled_font whilst emitting glyphs. 
We need to hold the scaled_font mutex whilst looking upon glyphs so lock
the font whilst iterating over the font subset.

4587e9e4f5 [scaled-font-subsets] Add locking to unscaled font. 
During map_glyph() we are passed a locked scaled_font for which we are
asked to add a glyph from that font into the active subsets for the
surface. This means that we eventually call scaled_glyph_lookup() to load
the glyph. But first, we attempt to find an existing an existing sub_font
for glyph, creating a new sub_font as necessary (possibly using an
entirely different unhinted scaled font). So before accessing the glyph
cache we need to make sure that we are holding the appropriate mutexes.

d3a6651237 [xlib] Set return code after failing to allocate glyph surface. 
Although we checked for an allocation error, we missed propagating the
status to the return error code.

bfc3a72cff [gstate] Propagate error from clip.

7975cf3f2c [paginated] Free local reference to target on error path. 
On the error path we must destroy the local reference to the target
surface.

4662204a2a [test-paginated] Fix double free of surface along error path. 
The ownership of the surface is transferred to the paginated surface, so
we do not need to destroy it ourselves along the error path.

bf3202fcfd [xlib] Fix double free of Pixmap along error path. 
If the paint fails then we attempt to free the Pixmap ourselves and via
the cairo_surface_destroy (as it also believes that it owns the Pixmap).

901f0b540c Review backend->create_similar() 
Avoid masking fatal errors by enforcing any error to be returned via an
error surface, so that the NULL return only means UNSUPPORTED. A few
backends called their create_similar() directly, without correctly checking
for a potential NULL (for example, the directfb backend was a timebomb,
since it used NULL to indicate out-of-memory).
